Corrosion of unspecified degree of lip(s), initial encounter

This code signifies chemical damage to the lip(s) where the specific severity of the injury (e.g., first, second, or third degree) is not documented. This type of injury results from contact with corrosive substances, leading to tissue destruction.

This code is appropriate for initial evaluations of patients presenting with chemical burns to the lips when the medical record does not specify the depth or extent of the corrosion. It should be used when the causative agent is a corrosive chemical, not a thermal burn.

• Ensure the documentation clearly indicates a chemical burn to the lip(s) and not a thermal burn.
• Only use this code for the initial encounter for treatment of the corrosion.
• If the degree of corrosion is specified, a more specific code should be selected.
